To date, the literature on revision ACLR surgery has primarily focused on comparing the outcomes to those of primary ACLR. While one-stage revision ACLR is well described and reported, few studies have reported the outcomes of two-stage revision ACLR. Neil Duplantier MD. There is no code for bone grafting. Her alignment, tibial slope and cartilage were all normal. Preoperative planning is critical to identify and characterize bone tunnel pathology. sharing sensitive information, make sure youre on a federal Clin Orthop Relat Res. The second stage of the revision ACLR was performed a minimum of 3 months later, after obtaining a CT demonstrating adequate filling of the tunnels using a hamstring autograft though a transtibial drilling technique. - Anatomic femoral tunnel drilling in anterior cruciate ligament reconstruction: use of an accessory medial portal versus traditional transtibial drilling Terms and Conditions, At a mean follow-up of 7.9years, clinical scores following revision ACLR did not differ significantly according to the tunnel size. They observed that an average of 5.8months was needed for healing of the autograft dowel to become visible on CT scans [11]. They reported that Si-CaP as a bone-graft substitute for tunnel augmentation showed favorable histologic, radiologic, and intraoperative integration comparable to the autologous iliac bone graft.

This provides a cylindrical graft, which is delivered to the femoral tunnel through the arthroscopic portal. official website and that any information you provide is encrypted Anterior cruciate ligament (ACL) reconstruction rates have increased over the past 20years to roughly 200,000 per year [1]. Morphometric analysis of femoral and tibial tunnel locations revealed that the two procedures were based on the same anatomical concept, and BPTB grafts showed significantly better anterior knee stability than HT grafts, although no significant differences in other objective evaluations and all subjective evaluations were detected between the two graft types in anatomical ACLR. ACL reconstruction is surgery to replace a torn anterior cruciate (KROO-she-ate) ligament (ACL) a major ligament in your knee. registered for member area and forum access.

The metaphyseal location and predominantly cancellous bone surrounding the graft tissue result in high osteoinductive and osteogenic potential from the hosts bone marrow [26]. Google Scholar, Group M, Ding DY, Zhang AL, Allen CR, Anderson AF, Cooper DE et al (2017) Subsequent surgery after revision anterior cruciate ligament reconstruction: rates and risk factors from a multicenter cohort. Increasing expectations from arthroscopic anterior cruciate ligament (ACL) reconstructions require precise knowledge of technical details such as minimum intra-femoral tunnel graft lengths. Am J Sports Med 45:17901798, Diermeier T, Herbst E, Braun S, Saracuz E, Voss A, Imhoff AB et al (2018) Outcomes after bone grafting in patients with and without ACL revision surgery: a retrospective study. Modified Transtibial Versus Anteromedial Portal Technique in Anatomic Single-Bundle Anterior Cruciate Ligament Reconstruction. At Mayo Clinic, we also are evaluating surgical techniques for ACL reconstruction, as well as optimal approaches to multiligament knee reconstruction. 2003 Jan;34(1):49-64. doi: 10.1016/s0030-5898(02)00070-6. PMC Although several popular techniques are currently in use, new methods are proposed for secure fixation of the tendon graft into the bone tunnel. Punch-biopsy specimens of the augmented tunnels were taken at the two-stage procedure, and histologic examination included quantitative analysis of the area of immature bone formation, lamellar bone, and bone marrow. Often the meniscus hasn't healed after the initial surgery, or lesions might have been overlooked during surgery, in particular meniscal root tears or meniscal ramp lesions. Numerous studies have reported that additional procedures (e.g., extra-articular tenodesis, anatomical anterolateral ligament (ALL) reconstruction) could be a meaningful option in cases of revision ACLR to improved rotatory stability which is associated with re-injury. We want our patients to be able to return to the activities they enjoy. -main criticism is that in some cases a transtibial tunnel will not allow for the exact desiredtunnel placement (you get what you get) Cite this article. 1998-2023 Mayo Foundation for Medical Education and Research.

It does not hit an edit, but be prepared for insurance to deny it. 2021 Nov 16;10(12):e2699-e2708. The bone grafting is an opportune time to do an osteotomy to correct the malalignment. - with a posteriorly positioned femoral tunnel consider final tibial graft fixation in full extension ratherthan 30 deg flexion, since positioning In 2-stage revisions, bone grafting of the tunnels may be undertaken if the primary position was inaccurate or if osteolysis has caused widening of the tunnels. American Journal of Sports Medicine. In addition, patients who receive revision ACL surgery might have other damaged ligaments. At a mean period of 33.9months, there was an improvement in the Lysholm score (77.215.5 vs 72.918.7), IKDC score (69.013.4 vs 69.313.4) and Tegner activity score (4.11.5 vs 4.61.2) for both groups. registered for member area and forum access. There has been a long-standing debate as to whether an autograft or an allograft should be used for revision ACLR. Arthrosc Tech. Am J Sports Med 47:324333, Chmielewski TL, Hurd WJ, Rudolph KS, Axe MJ, Snyder-Mackler L (2005) Perturbation training improves knee kinematics and reduces muscle co-contraction after complete unilateral anterior cruciate ligament rupture. % Successful revision surgery requires an understanding of the cause of failure, careful preoperative planning, meticulous surgical execution, proper postoperative rehabilitation, and appropriate patient counseling [4]. and transmitted securely. ]+yC`6Hd Ql]M 3w7ah;HNdyS*7x-zq^/4%^6eA$m@(,ly}U[N9E(/=iHCL")d6yx]K7!84,q!r~#6mE8dIS69eYn 7 0 obj - w/a right knee, place the tunnel at about the 9:30 to 10 oclock position; Primary ACL reconstruction is recognized as a successful procedure, but failure has been shown to occur in approximately 10% of patients.

Bookshelf In addition, we obtain single leg knee-to-ankle lateral X-rays to assess for any sagittal plane malalignment as well as to look for excessive tibial slope. Remaining soft tissue was debrided along tibia. doi: 10.1016/j.eats.2020.08.024. Tunnel orientation and size are the most important causes related to the two-stage procedure, as these enlarged tunnels may complicate graft placement and fixation [11, 12]. This site complies with the HONcode standard for trustworthy health information: verify here. They observed that the the failure rate was 10.3% in the one-stage revision group and 6.1% in the two-stage group. See our privacy policy. As this number has continued to increase, the incidence of revision ACL reconstruction (ACLR) has also grown to a rate of between 4.1 and 13.3% of all primary ACLRs performed [2]. Overview. They explained that because a bone tunnel of 15mm diameter with 45 of inclination resulted in a tibial tunnel aperture of >20mm, a 20-mm tunnel aperture was regarded as a candidate for grafting. Researchers randomly assigned 40 patients undergoing two-stage revision ACL reconstruction to receive either autologous iliac crest cancellous bone graft for tunnel grafting (control group; n=20) or silicate-substituted calcium phosphate in the form of sculptable microgranules (Actifuse MIS System, Baxter) as a bone graft substitute .
